The short version

  • Each has a real cost: Jenkins the controller is stateful and, in the open source distribution, has no high availability: build history, configuration and plugin state live on one filesystem, so every plugin upgrade and core update is downtime for every team using it, and a controller disk failure is a restore-from-backup event.; Listmonk it is not an email service provider. It hands mail to SMTP servers you configure and does nothing about IP warm-up, domain reputation, DKIM, DMARC or inbox placement, so deliverability failures are entirely yours to diagnose and fix.
  • They diverge on capability: Jenkins covers Plugin ecosystem, Listmonk covers Single binary deployment.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Jenkins

  • The controller is stateful and, in the open source distribution, has no high availability: build history, configuration and plugin state live on one filesystem, so every plugin upgrade and core update is downtime for every team using it, and a controller disk failure is a restore-from-backup event.
  • Capability comes from around 1,900 community plugins of very uneven maintenance, and the Jenkins security team regularly publishes advisories for plugins whose maintainer has gone; in some cases the advisory itself states that no fix is available and the only remedy is to stop using it.
  • Plugin upgrades are coupled: one plugin can require a newer core or a newer version of another plugin, so applying a single security fix cascades into a coordinated upgrade of a dozen components on a timetable you did not choose.
  • Pipelines are Groovy running under a sandbox and a continuation-passing-style transformation, so ordinary Groovy constructs sometimes fail in non-obvious ways, and the debugging skill you build transfers to no other CI system.
  • It is free to licence and expensive to run: somebody must own the controller, the agents, the Java version, the credentials store and the plugin upgrade cycle, and that recurring staff cost is the usual reason organisations move to hosted CI even when Jenkins works.
  • Leaving is costly by construction, because shared libraries, plugin-specific pipeline steps and accumulated freestyle jobs have no mechanical translation into GitHub Actions or GitLab CI, so the migration is a rewrite whose price grows every year you defer it.

Listmonk

  • It is not an email service provider. It hands mail to SMTP servers you configure and does nothing about IP warm-up, domain reputation, DKIM, DMARC or inbox placement, so deliverability failures are entirely yours to diagnose and fix.
  • Running it means running PostgreSQL, backups, upgrades and a mail relay, and the true cost is the engineering time to keep that stack healthy rather than the zero licence fee.
  • The campaign editor and analytics are basic next to Mailchimp or Klaviyo: reporting is limited to opens, clicks and bounces, with no revenue attribution, no ecommerce integration and no deep engagement scoring.
  • SQL-based segmentation puts audience definition beyond a non-technical marketer, so a marketing team without engineering support will be blocked on routine tasks.
  • The AGPLv3 licence obliges you to release source modifications if you offer the software as a network service, which is a real constraint for anyone considering embedding it in a commercial product.

What is Jenkins best used for?
Jenkins is most often used for builds that must touch physical hardware, such as embedded devices, test rigs or signing modules attached to a specific machine, air-gapped or heavily regulated environments where a hosted ci runner cannot be used at all, toolchains that hosted ci does not support, including node-locked commercial licences for eda, cad or simulation software, organisations with years of existing jenkins pipelines where the migration cost currently outweighs the operational cost of staying. Of those, builds that must touch physical hardware, such as embedded devices, test rigs or signing modules attached to a specific machine and air-gapped or heavily regulated environments where a hosted ci runner cannot be used at all are not what Listmonk is typically brought in for.

Answered from the vendors’ own pages

Jenkins: Why choose Jenkins over GitHub Actions or GitLab CI?

When the build needs something hosted runners cannot give you: physical hardware, an air-gapped network, a node-locked commercial tool licence, or an unusual platform. If none of those apply, hosted CI is usually less work to own.

Listmonk: Does Listmonk send my emails?

No. It composes, queues and tracks campaigns, then hands the messages to SMTP servers you provide, such as Amazon SES, Postmark or your own relay.

Jenkins: Can Jenkins run in high availability?

Not in the open source distribution, which runs a single active controller. High availability and active-active controllers are features of CloudBees' commercial products. Open source deployments mitigate it with fast restores and, sometimes, multiple independent controllers.

Listmonk: What does it cost to run?

The software is free. The real cost is a small server, a PostgreSQL database and per-email SMTP charges, which through SES are a fraction of hosted newsletter pricing at large list sizes.

Jenkins: How risky are the plugins?

This is the main operational risk. Many plugins have a single volunteer maintainer, and Jenkins publishes security advisories for unmaintained plugins where no fix exists. Auditing which plugins you depend on and who maintains them should be a periodic task, not a one-off.

Listmonk: What licence is it under?

AGPLv3, which requires you to publish modifications if you offer it as a network service to others.

Jenkins: Do I need to know Groovy?

For declarative pipelines you can go a long way without it. Anything involving shared libraries, conditional logic or custom steps is Groovy, and it runs in a sandboxed, transformed environment where standard Groovy idioms sometimes behave unexpectedly.

Listmonk: Is there an official hosted version?

No. Some unaffiliated providers offer managed Listmonk, but the maintainer does not run a hosted service.

Jenkins: What does it cost?

The software is free under the MIT licence. The cost is infrastructure and staff time to run controllers, agents and upgrades, plus a CloudBees subscription if you want high availability, support or centralised management of many controllers.
